Shree Krishna reiterates that His devotees reach Him quickly.  Firstly, with the personal form of God as the object of their devotion, they easily focus their mind and senses upon Him.  They engage their tongue and ears in chanting and hearing the divine Names of God, their eyes in seeing the image of His divine form, their body in performing actions for His pleasure, their mind in thinking of His wonderful Pastimes and Virtues, and their intellect in contemplating upon His Glories.  In this way, they quickly unite their consciousness with God.
Secondly, since such devotees continuously offer their hearts in uninterrupted bhakti, God quickly bestows His grace upon them and removes the obstacles on their path.  For those who are in communion with Him, He dispels their ignorance with the lamp of knowledge.  In this way, God Himself becomes the Savior of His devotees and delivers them from
mṛityu saṁsāra sāgarāt
(the cycle of life and death).
